But pretty blonde Danielle has since admitted that she hooked up with her ex because she had been drinking alcohol and wasn't thinking clearly - oops!
Danielle made the confession on her official Twitter page, after pictures surfaced of the pair kissing and flirting outrageously at Chelmsford's CTZN bar on Friday night (23 May).
While many presumed the pair were back together, Danielle took to social media to insist this isn't the case.
The reality star, who recently looked stunning in a blue jumpsuit at the Reveal Online Fashion Awards, wrote the message: "Feeling hungover today... Seeing your ex smashed and cringing at our heated convos alcohol defo makes u go with your heart not your head."
But rather than take this as a kick in the teeth, James leapt at the chance to continue their flirting...
The perma-tanned hunk quickly responded with the cheeky message: "Well I'm pleased u went with the alcohol Was good to see u like old times @Daniarmstrong88."
Danielle has so far not responded.
The glamorous Essex girl split up with James after he confessed to cheating on her in the last series of The Only Way Is Essex.
She recently told Reveal it was a "messy break up".

After admitting to her indiscretion on Twitter, Danielle's followers were quick to give their opinion.
Many girls emphasised with her situation, but advised her to stay strong. One wrote: "The heart always wins when you're drunk, but remember your head is always right! Men don't change, you're worth more than that! Stay headstrong." Another simple wrote: "Don't go back there!"
But a few fans hoped this meant a reconciliation was on the cards, posting comments like "you two should get back together; great couple."
